The Challenger 2 is the current Main Battle Tank of the British Army and represents the culmination of 80 years of tank design. In 1987, its design was presented to the Ministry of Defence in response to a requirement to replace the Chieftain MBT that had been partially superseded by the Challenger 1 MBT. Production began in 1993, and the tank finally entered service in 2002. The tank recently appeared in Iraq, where it proved indispensable during the battle of Basra. This book covers the evolution of the Challenger 2, from its origins and testing to its involvement in the Middle East and Iraq.
